Adobe/Adobe 代替のためのソフト+α (2017/11/23更新)

Adobeのためのソフトと関連しそうなソフトまとめです。

たぶん国内のまとめでは一番多く(また多機能)のソフトを紹介してるのでは?

Adobe代替を探してる方や学生さんに参考にしていただければ幸いです。(あくまでも、趣味範囲お金のない学生向けです。可能ならAdobeでまとめたほうが情報も多いし、ソフト間の連携シームレスになるのは言うまでもなく。)

基本無料か(性能・機能のわりに)安価ものです。

有名だけどあまり優秀でないと思ったもの記載してないものがあります。(ex, PixaSai、Paint.netMMD等)

カテゴリのとなりの()はAdobeではどのソフトかを表します。

対応OSWindowsLinuxのみです。

Macを私は持ってますがあまり好きでないのと、ほかの方にあまりお勧めできない(主にスペック面で)ため載せてません。

今回はCADについてはまとめませんでした。

単純に私があまり知らないのと、様々な用途が多くて分類が面倒なので。

機能や使い勝手自分で調べください。

感想?まとめ?

結構いっぱいありますね。

3DCGは絵を描けなくてもアニメーション動画簡単に作れる点が嬉しいですよね。

Blenderは多機能だけど操作が難しいですけど。

有償であればいろいろなメーカーから良いもがたくさん出てます。(Light Works、Cinema 4d等)

あと学生であればAutodeskの高性能なもの無償で使えます

以下その一覧

それぞれ梱包されてるのは違いますAutoCAD3ds MaxMaya、MotionBuilderなどプロ向けのが無償です。

CINEMA 4D学生無償で使えます

マカーならKritaやAffinity PhotoPixelmatorを組み合わせればアマチュアの方であればPSでなくてもいいのではと思えるほど。

CMYKでの編集可能ソフトPhotoshopだけでないですよ。

KritaとCorelDraw、Affinity Photo可能です。

Kritaは無料、Affinity Photo安価ですし。

ただしAffinity Photoペンタブ手ブレ補正はないです。(Kritaにはついてます。)

写真編集特にRaw現像ならあまりPhotoshopに拘る必要は無いと思ってます。(富士フィルムのような特殊メーカー使用してない限り。)

レタッチは確かにPhotoshopは強力ですけど、Affinity Photoも十二分な機能はあります

業務用でPhotoshopも使ってるという方以外は正直Affinityで問題ないと思います。(実際に私はそうです。)

VFXソフトはやっぱりAEが優れすぎてる感が。

フリーソフト有償ソフト無名のが多いです。

有名であってもUIや使い勝手はAEに落ちるものほとんどですし。

その点Blenderは多機能すぎますね。その分複雑だったりしますけど。

あとパワポKeynoteを使えば安易FXソフトになります

意外なのはVFX(プロジェクションマッピング)ソフトフリーのはほとんどないです。

安価にやるのであればiPad活用するといいと思います

Macの有料ソフトになりますがMadMapperとVDMX5の組み合わせは比較的分かりやすいです。

けどソフトが(内容を考えたら安いですが)この中では比較的高くなります

あとかなりのマシンスペック必要になるんでMacBookなら15インチモデルは欲しいですね。

DAW比較的容易に開発できるせいかフリーのもの新規のものが多いです。

たくさんあるので紹介しきれないので、私が一番いいと思ってるFL Studioとかなり安価Reaperのみ紹介します。(←追記で他のも加えました)

FLサポートを考えると非常に安いです。(最近ちょっと雲行きが怪しいのでは?となってる状況です。Sonar見たくひどい状態ではないのですが、Golという中の人移籍がどうとやら。)

ボカロ等と組み合わせれば優遇版も購入できますし。

ただEDMが得意で、生音源等は別途導入する必要がある場合があります

他のDAWソフトコスパだけなら中間グレードが一番コスパ良いと思います。(Cubase Artist、Studio One Artist等)

Mac向けのため上には記載してないですがLogicもかなり安いですよ。

ほかの用途ではお薦めはしてませんが、DAW用途Logicの為だけにMacを購入するのはありだと思います

Gravitは最近よくFireworks代替えとしても挙げられてますね。

他にもいいのがあれば教えてください。

追記していきたいです。

以上参考になればうれしいです。

Portable electronic equipment battery technology

1, about the trickle charge, rapid charging and stable battery charging algorithm

According to the energy requirements of the final application, a battery may contain up to 4 lithium ion or lithium polymer battery core, its configuration will have a variety of change, at the same time with a mainstream power adapter: direct adapter, USB interface or car charger. Remove the core quantity, core configuration or power adapter type difference, the battery has the same charge characteristics. So they charge algorithm. Lithium ion and li-ion polymer battery best charging algorithm can divided into three phases: trickle charge, rapid charging and stable charge.

trickle charge. For depth discharge core to charge. When core voltage in less than about 2.8 V, use a constant 0.1 C of the current charging for it.

fast charging. Core voltage trickle charge more than the threshold, improve the charging current rapid charging. Fast charging current should be lower than 1.0 C.

stable voltage. In the fast charging process, once the core 4.2 V voltage, stable voltage phase began. This is through the minimum charge current or timer or of the two joint to interrupt charge. When the minimum current below about 0.07 C, can interrupt charge. The timer is to rely on a default to trigger the timer interrupt.

Advanced battery charger with additional security function normally. For example, if the core temperature exceeds the given window, usually 0 ℃-45 ℃, charge will be suspended.

Remove some very low-end equipment, now on the market/li-ion polymer lithium ion battery solutions are integrated with the outer components or, in accordance with the characteristics of the charging to charge, this is not just to get better effect charge, but also for safety.

lithium ion/polymer battery charge is an example of applications-double input 1.2 A lithium battery charger LTC4097

LTC4097 can be used to exchange adapter or USB power supply for single quarter/polymer lithium ion battery. Figure 1 for double input 1.2 A lithium battery charger LTC4097 schemes. It USES constant current/constant voltage algorithm charging, from exchange adapter power charge, programmable filling up to 1.2 electric current A, and with USB power can be as high as 1 A, at the same time, automatic detection in each input voltage whether there. This device also provide USB the current limit. Applications include PDA, MP3 players, digital camera, light portable medical and test equipment and big color cellular phone. The performance characteristics: no external micro controller charging termination; The input power automatic detection and choice; Through the resistance from the exchange of charging adapter input can be as high as 1.2 A programming charge current; The resistance of programmable USB charging current is up to 1 A; 100% or 20% USB charging current set; The input power output and existing bias NTC (VNTC) pin as a 120 mA drive ability; NTC thermistors input (NTC) pin for temperature qualified charged; Pre-settings battery voltage with floating plus or minus 0.6% accuracy; Thermal regulation maximize charge rate and free hot air LTC4097 can be used to exchange adapter or USB power supply for single quarter/polymer lithium ion battery. The use of constant current/constant voltage algorithm charging, from exchange adapter power charge, programmable filling up to 1.2 electric current A, and with USB power can be as high as 1 A, at the same time, automatic detection in each input voltage whether there. This device also provide USB the current limit. Applications include PDA, MP3 players, digital camera, light portable medical and test equipment and big color cellular phone.

2, lithium ion/polymer battery scheme

Lithium ion/polymer battery charge scheme for different number of core, core configuration, and power types are different. At present mainly have three main charging scheme: linear, Buck (step-down) switch and SEPIC (booster and step-down) switch.

2.1 linear scheme

When the input voltage in big with the charger with sufficient clearance of core after opening voltage, it is linear scheme, especially 1.0 C fast charging current than 1 A big too much. For example, MP3 players usually only one core, capacity from 700 to 1500 mAh differ, full charge voltage is open 4.2 V. MP3 player power is usually the AC/DC adapter or USB interface, the output is the rule of 5 V; At this time, the linear scheme is the most simple, most charger of the efficiency of the scheme. Figure 2 shows for lithium ion/polymer battery solution linear scheme, basic structure and linear voltage neat device.

linear scheme charger application examples-double input Li + charger and intelligent power source selector MAX8677A

MAX8677A is double input USB/AC adapter linear charger, built-in Smart Power Selector, used for rechargeable single quarter by Li + batteries portable devices. The charger integration of the battery and the external power source and load switch charging all the power switch, so that no external MOSFET. MAX8677A ideal used in portable devices, such as smart phones, PDA, portable media players, GPS navigation equipment, digital camera, and digital cameras.

MAX8677A can work in independent USB and the power input AC adapter or two input either one of the input. When connecting external power supply, intelligent power source selector allows the system not connect battery or can and depth discharge battery connection. Intelligent power source selector will automatically switch to the battery system load, use the system did not use the input power supply parts for battery, make full use of limited USB and adapter power supply input. All the needed electric current detection circuit, including the integration of the power switch, all integration in the piece. DC input current highest limit can be adjusted to 2 A and DC and USB input all can support 100 mA, 500 mA, and USB hung mode. Charge current can be adjusted to as high as 1.5 A, thus support wide range of battery capacitive. Other features include MAX8677A thermal regulation, over-voltage protection, charging status and fault output, power supply good surveillance, battery thermistors surveillance, and charging timer. MAX8677A using save a space, hot enhanced, 4 mm x 4 mm, 24 of the pins TQFN encapsulation, regulations, work in exceptional temperature range (40 ~ + 85 ℃).

2.2 Buck (step-down) switch scheme

When A 1.0 C of the charging current more than 1 A, or the input voltage of the core than with high voltage open many, Buck or step-down plan is A better choice. For example, based on the hard drive in the PMP, often use single core lithium ion battery, the full of open is 4.2 V voltage, capacity from 1200 to 2400 mAh range. And now PMP is usually use the car kit to charge, its output voltage in a 9 V to 16 between V. In the input voltage and battery voltage is the voltage difference between high (minimum 4.8 V) will make linear scheme lowers efficiency. This kind of low efficiency, plus more than 1.2 A 1 C fast charging electric current, have serious heat dissipation problems. To avoid this kind of situation, will the Buck scheme. Figure 3 for lithium ion/polymer battery charger scheme Buck diagram, basic structure with Buck (step-down) switching voltage regulators completely the same.

2.3 SEPIC (booster and step-down) switch scheme

In some use of three or four lithium ion/polymer core series equipments, charger of the input voltage is not always greater than the battery voltage. For example, laptop computers use 3 core lithium ion battery, full charge voltage is open 12.6 V (4.2 V x3), capacity is 1800 mAh to 3600 mAh from. Power supply input or output voltage is 1 6 V AC/DC adapter, or is car kit, the output voltage in a 9 V to 16 between V. Apparently, the linear and Buck solutions are not for this group of batteries. This is about to use SEPIC scheme, it can in the output voltage is higher than when the battery voltage, can be in the output voltage less than when the battery.

3, and power detection algorithm is proposed

Many portable products use voltage measurements to estimate the remaining battery power, but the battery voltage and surplus power relationship but will with the discharge rate, temperature and battery aging degree of change, make this kind of method can top 50% margin of error. The market for longer to use product demand unceasingly strengthens, so the system design personnel need more accurate solution. Use capacity check plan come to measure battery or consumption of electricity, will be in a wide range of application power to provide more accurate estimate of the battery power.

3.1 power detection algorithm is one of the examples of application, function complete list, double the battery portable battery application design

power detection principle. Good capacity check plan at least to have battery voltage, temperature and battery electric current, measuring method; A micro 9 a; And a set of and the verification of the punishment power detection algorithm is proposed. Bq2650x and bq27x00 is full capacity check program function, with a measuring voltage and temperature of the digital converter (ADC) and a measuring electric current and charging sensor the asp. These capacity check plan also has a microprocessor, is responsible for the implementation of the Texas instruments power detection algorithm is proposed. The algorithm can compensate the lithium ion battery life.low self-discharge, aging, the temperature and discharge rate, and other factors. Chip embedded microprocessor as host system processor save these calculation burden. Capacity check program can provide remaining power state information, bq27x00 series products also offer surplus can Run Time (Run Time to Empty) host may at any Time to capacity check plan these information query, then LED indicator light through or displays will inform the user battery. Capacity check meter is very easy to use, the system processor need only configuration 12 C or HDQ communication drive can.

The battery circuit description. Figure 4 (a) can be used for identification of IC functions with typical application circuit batteries. According to the use of IC testing program is different, the battery needs to have at least three to four outside the terminal.

VCC and BAT pins will even to the battery voltage, so that for, C power and the battery voltage measurement. The battery is connected a grounding resistance smaller detection resistors, let capacity check meter high impedance SRP and SRN input can monitor sensor resistance on both ends of the voltage. Through testing the current flows through a resistor can be used to judge the battery or release the amount of electricity. Designers choose detection resistance value must be considered when resistance on both ends of the voltage can't more than 100 mV, low resistance may be more hours in current errors. Circuit board layout must ensure that SRP and SRN to testing from as close as possible to the connection of the resistor sensor resistance end; In other words, they should be the Kelvin attachment.

HDQ pin need external and resistors, this resistance should be located the host or the main application, such capacity check plan to the battery and portable devices when sleep function enable connection broken. Advice and resistance choose 10 k Ω.

battery identification. A low cost WeiMao batteries are getting more and more serious, these cells may not contain OEM requirements of security protection circuit. So, genuine battery may contain figure 4 (a) shows the appraisal circuit. When to identify the battery, the host to contain IC (bq26150, the function is cyclic redundancy check (CRC)) issued the battery packs a ask value (challenge), the CRC will contain battery according to this inquiry value and, in the building of the IC in CRC polynomial calculation the CRC value. CRC is based on the host of command and IC secret in the query of the definition of the CRC polynomial completed, the host in CRC values calculated with the calculation result of well battery comparison to identify the appraisal success.

Once the battery through the appraisal, bq26150 will issue commands to ensure that the host and quantity test plan of material lines between normal communication. When the battery connection interruption or to connect, the whole the identification process will be repeated again.

double the battery application. Figure 4 (b) for use bq26500 support double the typical application of lithium ion battery circuit. In order to support more battery, and this circuit is adding a adjustable regulators. Capacity check millions of BAT pin and the bottom of a battery anode linked to complete the variable voltage measurement of the battery.

Host to be able to read capacity check plan of variable voltage measurement battery, to make sure the end of discharging threshold and charging terminate threshold. As for the remaining state power (RemainingStateofCapacity), do not need to read can use directly.

The above bq2650x and bq27x00 etc capacity check plan provides the battery manufacturer a simple to use options, this scheme L [just measuring battery voltage to be precise, so these capacity check plan can be applied to various battery framework, and can support the battery identification and double the battery application '

3.2 power detection algorithm is an example of applications another, can apply to all kinds of general voltmeter new IC.

Today's many manufacturers can provide a variety of voltmeter IC,, the user can choose the suitable function device, to optimize the product price. Use voltmeter measurement of storage battery parameters, the separate architecture allows users in the host custom power measurement algorithm within. Eliminating embedded processor battery cost. On this to Dallase semicconductor company called cases of DS2762 chip for typical analysis. A new separate voltmeter IC, its structure see chart 5 (a) below.

DS2762 application characteristics

DS2762 is a single quarter of lithium battery voltmeter and protection circuit, integrated into a tiny 2.46 mm x 2.74 mm inversion of packaging. Due to internal integration for power detection of high precise resistance, this device is very save a space. It is the small size and incomparable high level of integration, for mobile phone battery and other similar handheld products, such as PDA, etc, are all very ideal. Integrated protection circuit continuously monitoring the battery voltage, over voltage and flow fault (charging or discharge period). Different from the independent protection IC, DS2762 allow main processor surveillance/control protection FET conduction state, such, can DS2762 through the protection of the power system and the control circuit implementation. DS2762 can also charge a battery consumption has depth, when the battery voltage within three V, provide a limit of the charging current recovery path.

DS2762 accurate monitoring battery current, voltage and temperature, the dynamic range and resolution of common satisfy any mobile communication product testing standards. The measurement of current for internally generated when the integral, realize the power measurement. Through the real-time, continuous automatic disorders correct, the precision of power measurement can be increased. The built-in measuring resistance due to eliminate manufacturing process and temperature and cause resistance change, further improve the precision of the voltmeter. Important data stored in 32 bytes, can add the lock EEPROM; 16 bytes of SRAM are used to keep dynamic data. And DS2762 all communication all through the 1-Wire, more communication interface node, minimize the battery and the connection to the host. Its main features for; Single quarter of lithium battery protector; High precision current (power measurement), voltage and temperature measurement; Optional integrated 25 m Ω measuring resistance, each DS2762 after fine-tuning alone; 0 V battery restore charge; 32 bytes can lock EEPROM, 16 bytes SRAM, 64 a ROM;

仮に年月が経過して一般的なPCの性能が向上し、相対的にPS3の処理能力が陳腐化したとしてコストパフォーマンスの面で断然有利。PS3本体とソフト価格の合計5万円弱で、同等の環境PCで揃えるのは至難。時間が経てば本体価格も下がっていくだろうし。

(3)ストレージインターフェース

全てのパッケージHDDが標準搭載で、今月からは80GBが標準になり、しかもその気になればさらに大容量の市販のHDD換装可能。よって素材となるファイルストレージしては容量面も拡張性も十分。また「PLAYSTATION Eye」といったUSBカメラで直接の素材取り込み手段もある。

(4)対応形式

一般的なMPEG1、2のみならずh.264DivX再生に対応しているので、出力形式の対応も敷居は低いのでは。

(5)動画共有サイトとの連携

PS3ソフトまいにちいっしょ」には、ゲーム内を録画してYouTubeアップロードする機能があり、他のメーカーに提供されている開発環境にもこの機能は含まれていると聞く。よって制作した動画や音声をシームレスYouTubeアップロードする事も可能なのでは。

(6)PlayStation Homeとの連携

制作した動画をフレンドに送ったり、制作者のhomeでフレンドを呼んで上映するといった機能も実現可能なはず。もしくは、ソフトそのものにストリーミングサーバの機能を付加するというのもアリかも。

(7)オンラインアップデート

当然ながら可能だろう。

(8)競合ハードが参入不可能な分野

大容量ストレージと高性能CPUが必須のソフトなのでWiiにはまず不可能だろう。可能性があるとすればXbox360だが、(3)は専用HDDしか選択肢がなく価格も高価。(5)は今のところ実績は無く、PS3に十分なアドバンテージが見込める。


YouTubeニコニコ動画など、ユーザが作成する動画コンテンツ(CGMとか言うんだっけ)の隆盛は今後も続くと思われるので、その分野で一定の地位を確立するのも将来的にも有益ではないかと思うが、いかがだろうか。
