I've managed to copy a brief 3 minute VHS video extract into a Powerpoint presentation using Movie Player 2 (.wmv file) and played it today in front of a class. There were two problems: 1. the audio was too low (the amplified speakers are '160 watts PMPO' - are they the problem?) 2. The frames didn't run smoothly. Is this because the compression ratio is too high or the processor on my laptop (Celeron 1100mhz) too slow?
Jerky playback on the laptop? Probably due to the graphics ability of the puter,poor sound is often due to the audio track not being "Normalised"(If there is any music,chances are it will be very loud)I find my puter(playing back DVD's I have created)plays the music uncomfortably loud,but the speech always sounds low.I haven't had chance to search the web for an "Audio Normaliser" although I used to have one for MP3's.This will set the whole audio spectrum to nearer 100%(amplifies quiet,lowers loud sounds)If its audio is .wav then its possible to use the OS's "Sound Recorder"
These will be captured as AVI files. which, when played in Powerpoint will be poor quality and jerky with variations in sound volume/quality.
To overcome this the clip needs to be encoded to MPEG2 format - use TMPEGEnc for this click here for the free download.
One word of warning....check that it plays on the work PC as sometimes they will be using different codex to those on your PC - not a common problem but one I have regularly because I never leave things alone! (My IT dept. end up cursing while downloading the new codex)
The three minute clip will take several minutes to encode (up to an hour depending on PC spec.) and I suggest that you DON'T multitask while its going on as encoding can be resource hungry
I downloaded the software and think I encoded it to MPEG2 but the application didn't seem to recongise .wmv files. Anyway, it converted my movie file into an .mcf file which doesn't seem to be a digital video file at all.
