Hi,

We are looking for a tool allowing us to objectively compare various video codecs and settings in order to determine which one will best fit our needs. I am mostly interested in comparing QT codecs and I don't want to rely exclusively on subjective feedback.

Is there any Peak Signal-to-Noise Ratio, Video Quality Metric or any other method which would work on QuickTime video files (even if we need to convert back the QT video to raw format in order to analyze it).

Thank you in advance for your insights and suggestions.

Regards,

Guillaume

PS: For audio, we are using the QSSP audio visualization component created by Totally Hip, it allows us to view, adjust and compare real-time spectrogram/waveform and power spectrum on any audio codec supported by QuickTime._______________________________________________
