Movies

Movies in PS3's GTs uses PAMF, a Sony format.


Movie Playback

Decryption

Movies are normally encrypted using Salsa20. Assuming you've found the key in Base64 format (or hex), you can use GTToolsSharp to decrypt it.

Note

In GT6, the keys for movies can be found in the database/gt6/menudb.dat SQLite database, in the t_movie table.

Decrypt command
GTToolsSharp cryptmovie -i <movie_file_path> -k <key as base64 string, or hex string>

If decrypted successfully the file header should show PAMF.

PAMF playback

PAMF Tools from PS3 SDK is required, you will have to find that yourself.

After that, you can use PS3StreamViewer to open and play a movie file.


Movie Creation

Requirements

  • FFmpeg, used to convert a video to the appropriate pixel format
  • PAMF Tools from PS3 SDK (you will have to find that yourself)
  • A source video to convert to PAMF.

To convert to PAMF you will need to prepare your input video into specific formats.

Video

Video material file should be in .avi, in YUV2 format. This can be done in ffmpeg through the following command:

Converting to YUV2 with FFmpeg
ffmpeg -i <input_file> -b:v <bit_rate> -pix_fmt yuv420p <output_file>

Where:

  • input_file is your original video file
  • bit_rate is the target video bit rate, which should match the original video file - this will control the quality of the converted video. Example: 2200k for 2200 kbits
  • You can run ffprobe <input_file> to find out the original bit rate, example: "Duration: 00:00:42.66, start: 0.000000, bitrate: 2113 kb/s"
  • <output_file> is the output file, which must ends by .avi. Example: output_video.avi

Audio Track

You also need to extract the audio track from the original video unless you already have it seperated. This is done with:

Extracting the audio track
ffmpeg -i <input_file> -vn -acodec pcm_s16le -ar 48000 -ac 2 <output_file>

Where:

  • input_file is your original video file
  • <output_file> is the output file, which must ends by .wav. Example: output_audio.wav

Tip

You can (and should) also tweak the ffmpeg arguments to your requirements/liking.

Creating the PAM

Now that you (hopefully) have one AVI, and one WAV file, you can proceed to create the PAM file.

  • Open PS3 Stream Composer.
  • In File, click on New.
  • Fill in Clip Name and Project Name with anything you want, then press Next. Tweak anything if you need to after that, and/or just press Finish.
  • On the left, you should see a pane named Clip Setting. Expand Video, then you should be able to see Stream #1. Right click on it, then click on Video Source Setting.
  • Click Open, then select the AVI file you made earlier. If everything is correct your should be able to see the video lengths and some other details. Press OK.
  • Now in the Clip Setting pane, Expand Audio, right click on Stream #1 and click on Audio Source Setting.
  • Same thing here, open then select your WAV file you made earlier, then OK.
  • Both should now display as Not Encoded.
  • At the top bar, look for Run, then click on Encode + Multiplex + PAMF Compose. This will create your PAMF file. Depending on your PC specs, this may take a while.
  • Once done, PAMF file should be created. In File Explorer, head to Documents, then PLAYSTATION(R)3 Stream Composer\MuxWork\<project_name>\<project_name>. If you see a PAM file, you're done.
