ffmpeg should be able to do it. A command line something like this: ffmpeg -i input.mp4 -vcodec copy -acodec aac -strict experimental -ac 2 -ar 44100 -ab 192k output.mp4

I'd stick to the HDTV 1080p presets. I don't know why they put in YouTube presets, but if those really affect the quality of your videos, I wouldn't recommend them. I've uploaded a few 1080p videos to YouTube, and it hasn't changed the resolution to 720p. Although my workflow included exporting a high-quality version from Premiere, and then re-encoding with ...

This is probably not the best place for your question, but anyway... Do you need a home video editing solution, or a professional tool? Some may argue whether FCP is truly professional, but anyway it is used as such by many editors. (the latest version X is not quite ready yet for Pro use, but probably will be eventually) On Linux, there is nothing ...

in reality you gain very little or no performance boost with nvidia cuda or ati stream technology in editing unless you use their professional cards which are specifically made for editing work. you can see a list at http://www.adobe.com/products/premiere/systemreqs/ Adobe-certified NVIDIA GPU card for GPU-accelerated performance all the other cards there ...

Adobe Premiere is a resources hog, for all machine resources : memory, disk & cpu. If your O/S is 64-bits, then 8GB should be enough. The page file is not significant, since there won't be any memory swaps (if there are you should add memory). The only advice left is to put input and output on separate physical drives (real drives, not partitions). ...

The solution is to set the Work Area accordingly. Use the second pair of sliders below the timeline. They will snap to the edges of the clip. Then, in the export dialog, as Source Range, select Work Area.

This can be done using ffmpeg with its crop filter. Using a command line tool makes it easy to automate the process or run it from another program or script. It also has a library API. These commands will create the four videos, one for each quadrant, each with a full copy of the audio. (Use -an instead of -acodec copy to drop the audio.) You can use ...

What you are actually looking for is an 'intermediate format'. For audio, this normally means uncompressing it to PCM audio (well, ideally it should mean not compressing it in the first place): ffmpeg -i input.file -c:a pcm_s16le output.wav For video... well, it's sometimes possible to use either raw video or a lossless codec like huffyuv, but generally ...

Ok, firstly I'd recommend always that you are in the editing stage, to save the edits as AVI Uncompressed. (sometimes named as "full frames") . Every time you use a non lossless codec, which are the majority, you will apply a quality loss in every save. Similar than is no good (except in some circumstances and with some tools) editing a JPG. (I've done when ...

You can use the razor tool to split the clip at the begin and end points of the section that you want to slow down. Then apply the speed option to the that sub-clip.

You can do a few things. Under Project menu look for "remove unused clips" or something similar. Also, you can create a trimmed project from that file as well. I would recommend also, wrapping the videos into a larger single video file, so Premiere doesn't have to keep track of so many files internally. This makes a difference in my experience. You can ...

First make sure you have the same project settings at the Audio tab. for example 32khz, 16bit,mono... Also wait a while after you place a video clip on your timeline before you hit PLAY. Sometimes Adobe premiere needs to render-cache audio to be able to work properly.

The short answer is that HT almost never makes a significant performance impact. Intel claims 15% performance increases under ideal conditions. Compared to the difference between a modern Core i5 or Core i7 and an ancient Q8200, 15% is not worth worrying about. The i5-2500K has about twice the performance of the Q8200. The i7-2600K has almost three times the ...

You should try using Camatasia Studio with a lower resolution. You could also try installing these codecs.

I would use a version control software such as cvs, svn or git, git probably being the fastest and easiest. These are command line tools hat do all of the above operations (check in/ out, lock, synchronize work, etc). These are typically used for software projects but can be used for any type of project. If you are not command line saavy there are a ton of ...

Adobe has some very detailed articles on troubleshooting freezing issues and a myriad of other things with Premiere, you can find it here (Vista) or here (XP). If none of that helps whatsoever, check the running process with Process Explorer to see what exactly it is doing on startup. A defrag, cclean, and virus scan wouldn't hurt much either.

I usually start at YouTube when I'm looking for videos.

This depends on which version you're using. I know GPU acceleration is supported in the newer CS4 products. From the above link: Note: For details regarding GPU support of individual Adobe products, please visit that product's system requirements page on the Adobe website. They also show a list of compatible video cards. By entry level, it ...

If you want to enable typing in Chinese on Windows, this is how I enable it (works on past versions of Windows- not sure about Windows 7, but could be helpful for other users on Superuser): Start Menu > Control Panel > Regional and Language Options Select the "Language" Tab Check the box that says "Install files for East Asian Language" Select "Apply" ...

If you need the keyboard to type Simplified Chinese, without having to download anything, see if your Win7 Pro/Home Premium already has Chinese. Go to Control Panel/Clock, Language, and Region/Region and Language/Change keyboards or other input methods. to the "Keyboards and Languages" tab, click "Change Keyboards..." button. In to "General" tab and ...

Depending on your operating system, you need to put the files here: Windows: C:\Program Files\Adobe\Common\Plug-Ins\CS6\MediaCore\ OS X: /Library/Application Support/Adobe/Common/Plug-Ins/CS6/MediaCore/ Copy them there, and don't forget to restart Premiere Pro to have them recognized.

Levels are (agreed upon) constraints put on an encoder. They limit the encoder to certain frame sizes and bit rates in order to make sure that a decoder can correctly decode such a bitstream. This means that a decoder that claims to be compatible with level X bitstreams must be able to decode a stream encoded with level X. You can find an overview of all ...

This may be of some interest: Lightworks It is out for Linux (open sourced even!) in November and has quite a list of production credits

The only thing I ended up being able to do, and this is very stupid, was choose to upload the video to my YouTube channel (privately) and then download a working MP4 from them.

This is a very complex question well beyond a simple answer without knowing your PC's specs and CS6 setting. You might want to investigate CUDA acceleration in CS6 on Google or the Adobe help pages. Basically, if you have an nVidia CUDA supported/accelerated card in your pc, all video scrubbing, editing will be in real time, like you want it to be. You ...

I don't have a full answer, but I do know that mencoder and ffmpeg are two of the most standard tools out there. When transcoding, you're likely best off using one of those tools to perform the actual transcode. Both of those tools are command line. GUIs exist for them, and I believe a large number of the available tools on the market actually use one or ...
