Audio disappearing partway thru imported clips
Hello all,
I’m new to Premiere Pro (but a longtime editor with Avid and FCP), and I could use some help.
I am using Premiere Pro CS3 under Vista Home Premium Sp1 on a HP Core2 Quad CPU Q6700 with 6 GB Ram.
I am editing clips captured using FRAPS (a screen capture utility) at 1440×900, 48kHz Stereo audio. FRAPS creates AVI files in the FPS1 codec, which is installed with FRAPS. I created a custom preset in PPro, 1440×900 square pixel, 24 fps, which matches the FRAPs clips.
I imported the AVI files and started editing. After a time, the audio from several of the clips disappeared. More specifically, in 3 of the 7 clips I imported the audio disappears at 1:09 in the clip. That is, when looking at the waveform of the clip in the viewer, the audio stops at exactly 1:09 (33 frames in) in all 3 clips which have this problem.
If I play these same clips in Windows Media Player or in Adobe Bridge, the audio is present throughout the clip. I tried making 1 of them offline then relinking it, but it didn’t change anything.
I say ‘after a time’, because I can’t be 100% sure that I played the problematic clips and heard the audio or not. I think I did, meaning that the clip played with audio at least once and then developed this problem, but I am not positive.
Any insight or suggestions would be most welcome.
Thanks in advance! -

Although you have the FRAPS codecs installed on your system, Premiere doesn’t like them. You need to use an intermediate codec.
Either decompress, or recompress to a Premiere-friendly lossless codec prior to import.
I use AVS Video Converter to decompress almost everything, including FRAPS.Vince

Thanks! Can you recommend a codec? I’m editing captured video game footage at 1440×900, 24fps. (I’m using 24fps mainly to keep file sizes down, as temporal resolution isn’t an important factor to me.) All my experience is with Avid (proprietary codecs) and FCP (ProRes, DV, and DVCProHD, mainly), so I’m grateful for your input.

I use ‘Uncompressed’ or ‘Compressor: None: (AVI or MOV).
This requires the least amount of processor power needed for playback, which means easier editing.
You do need a decent amount of drive space, as the files are huge (I think Gimongous is the technical term??).I haven’t tried any Lossless Compressed codecs, other than using MS Video 1 for classic games which are usually limited to 256 colors, which won’t work for you.
If you find a suitable PP compatible Lossless Intermediate codec for modern video game editing, I’d love to know. 🙂Vince
