    I had super 8 films transferred to uncompressed avi files. The size of a 3m20s file is about 750 MB.

    I would like to cut them, put a simple title at the beginning of each file and compress them is something more usable.

    Could someone advise me in what format should I convert those files, which settings and what software to use.

    Thanks a lot.

    Details of the file:

    ID : 0
    Format : DV
    Commercial name : DVCPRO
    Codec ID : dvsd
    Codec ID/Hint : Sony
    Duration : 3mn 22s
    Bit rate mode : Constant
    Bit rate : 24.4 Mbps
    Encoded bit rate : 28.8 Mbps
    Width : 720 pixels
    Height : 576 pixels
    Display aspect ratio : 4:3
    Original display aspect ratio : 4:3
    Frame rate mode : Constant
    Frame rate : 25.000 fps
    Standard : PAL
    Color space : YUV
    Chroma subsampling : 4:2:0
    Bit depth : 8 bits
    Scan type : Interlaced
    Scan order : Bottom Field First
    Compression mode : Lossy
    Bits/(Pixel*Frame) : 2.357
    Time code of first frame : 03:06:16:17
    Time code source : Subcode time code
    Stream size : 695 MiB (95%)

    There is no audio on my original Super 8

    I hate to break it to you, but those files ARE compressed. With DV compression (~5.5:1, compared to uncompressed 4:2:2 YUV, or ~8.25:1 compared to uncompressed 4:4:4 RGB).

    Any decent NLE, even WMM, should be able to do what you are asking with those files. For economical but powerful, I would recommend Sony Movie Studio.

    Your choice of what format to convert to should be driven by what works best for your existing or near future hardware, though avc/aac in mp4 is a safe common bet these days.

    If you want to use an AviSynth based converter (like StaxRip or MeGUI), they will probably be able to read the DV video content using the FFMS2 or L-SMASH Works plugin; or you can install any DV VfW codec (e.g. ffdshow, enabling DV in its VFW Configuration of the decoder) to be able to convert it with most VfW compatible converters.

    Well, many other tools will support VfW. Installing a DV codec will probably enable them to read DV video streams in an AVI container.

    Where did he ever say he/his computer could not read them? Du konntest in deutscher Sprache reden, und er würde dich mehr verstehen.

    Thanks for the info. I will use the movie studio.
    I have tried a simple converter but the quality of the converted file was bad. I had to change the bitrate 10000 to get a correct quality but the file size was almost the same. Is there another setting that I missed?

    My computer read the file correctly.

    Something that you missed? Probably, but I wouldn't know what that might be at this casual a glance. GIGO.

    IOW, I would need much more info, particularly a detailed MediaInfo text readout of the source AND target files. Maybe even direct clips.

    OK, most usual issue is that someone is unable to read a source format...

    So, let me try a different approach ... which target format is more compatible? — Probably DVD Video. DV is certainly interlaced, Bottom Field First; was the original Super8 video too? That should be detected with certainty before setting up an MPEG2 encoder (e.g. HC) if you decide to author a simple DVD (with e.g. IfoEdit or GUI for DVDAuthor ...).

    An MP4 with AVC video stream is more efficient, though. But I am not sure if playback of interlaced AVC is very compatible on different consumer players.

    ?? If I was going to convert it, I'd use MeGUI.

    How does his computer read them? DirectShow, VFW, a self contained media player etc? Even if "his computer can read them" how does it guarantee every conversion program can?
    My computer can decode AC3 audio, but VirtualDub refuses to acknowledge AC3 exists until I install the VirtualDub AC3 plugin.

  13. Load that DV vide into Sony Vegas, as you did, set project to DV PAL, cut it, add those titles if you want, and export it again as DV avi. Render As/ Video for Windows/PAL DV. This you can archive also, because export is the same as original (except those parts with title added).

    Then you export it again in Vegas into mp4, as you say, so it is more usable, but your Vegas will most likely not let you export interlace mp4, like original, with proper aspect ratio. I don't think you can set PAL DV avi aspect ratio for mp4 (in your Vegas, but I could be wrong).

    You probably have to export to mp4 Render As/MainConcept mpeg4 and frame rate 25p - setting field order to none, check if there is such a thing like PAL square pixel in frame size setting. 25p is not that fluent as your source 25i .

    Or you try to manually type 50p for frame rate, that video would be much more fluent, but the trouble is, I'm not sure if that Vegas Studio will export 50p, probably not.

    Export to mpeg2, MainConcept mpeg2, it will let you set 25i, so video will be fluent, there is special template for you video format - DVD PAL template, export mpg.

    Thank you for the advices and sorry for the late reply. I was quite busy before I could return to those videos projects.

    I started to use Vegas but I got so confused with all the options and couldn't get a file a correct file. (either too big file or with a visual loss of quality compared to the original). So I only used Vegas to insert titles.

    I finally used Movie Maker to convert the files and removing the sound. The result seems correct.
    I have converted the file to MP4 using H264.

    However, I would like to ask some advice:

    The original file is 720 x 576 p. I have kept the same. But is it better to increase the resolution while keeping the aspect ratio?

    For the debit, I used 8000Kbits/s. Is it ok?

    I used 29.97 frame per second. The original file was 25fps. Is it not better to use the original one?

    If you have any comments regarding other settings, please let me know

    Below is the converted file details. In my first post, at the top of this page, there are the details of the original file.

    Thank you.
