  1. Thanks for that. As an alternative work-through, what about using Handbrake (or similar) to change the frame rate of the 25fps clips to 29.97 prior to compiling with the 23.98 clips. would it then be possible to go 'full NTSC' on the whole contents with Toast 15?

  2. I have some videos I'd like to compile on a disk for a friend in the USA (so NTSC format) - they are 1280 x 720p and either 25fps or 23.98 fps but although I'm selecting NTSC in Preferences, when I come to the burning stage a box pops up to tell me I'm about to burn a mixed PAL/NTSC disk. I don't think this will work well for my friend Stateside.

    Ought I to 'pre-convert' some of the clips in order to avoid this, if so using what software for the best and with what settings?

    I have some HD footage that I wish to record to a blank BD disc (approx 23gb of material) but on attempting either to burn the stuff to disk directly or make a disk image first, the process is quickly interrupted by a system message: "Could not record the disc because there was not enough memory." and "Result Code = -108". I currently use a 21.5in (Late 2013) iMac with 8gb total RAM. Having just performed a very similar exercise with some other HD footage of mine without a hiccup I'm left wondering why this has cropped up now? Or how to remedy it?
    Here's a screenshot of Toast with the material assembled.







    23.976 fps is the framerate normally associated with NTSC progressive. (29.97 fps is NTSC interlaced.)

    While 23.976 fps is a perfectly valid framerate for DVD, Toast will use either 29.97 fps (NTSC) or 25 fps (PAL), when converting the video. Unfortunate, but those are the breaks when using this product.


    The only way to have Toast preserve the 23.976 fps framerate, is when you feed Toast a DVD compliant MPEG-2 file (with soft 3:2 pulldown marker), in order to avoid any conversion by Toast. You could convert your file with another tool that exports to DVD specification, e.g. iFFmpeg.


    If you let Toast convert the framerate, you should prefer 29.97 over 25 fps, as the first will be smoother: the 3:2 pulldown is applied to the first for maximum smoothness, while the latter has no scheme that is that much optimised. A modern tv set may use its own trickery to make the motion more smooth, but those effects may differ from tv set to tv set. And those would work best on the original framerate, not a converted framerate.


    Toast's framerate conversion isn't particularly bad compared to others, but something is lost that could have been preserved.


    Thanks for the interesting suggestions. OK, so were I to take the 23.976 fps file and run it thru iFFmpeg, resulting in an MPEG-2 file, how then would I record it to DVD in Toast?

  5. Hi folks,

    I have an item that is 1280x720 but 23.98 fps. I wish to burn it to DVD but I'm unsure whether to select 25fps (PAL) or 29.97 (NTSC) in Toast Video Preferences. I will be playing back the resultant DVD on a UK DVD player/TV. I'd like to know from someone more knowledgable than me which is the preferable format to burn to? I should mention in passing that NTSC DVDs are playable in all UK DVD players - the signal is transcoded, what I'm concerned most about is avoiding a jerky playback picture. For instance, should I change the frame-rate, prior to mastering to DVD, using a program like Handbrake? Any hints or tips on this gratefully received!
