How to convert bitrate of video to at least 50 mb/s?

[GroundHogSOS]

I am trying to convert a video so that it has a bitrate of at least 50 mb/s. Someone recommended me to use Streamclip, so I downloaded version 1.2. The problem is that when I tried to convert the bitrate, it turned out to be more difficult than it should be.

I tried to convert it via Avid DNxHD, but it would not let me select the bitrate. I tried switching to other compressors, such as h.264, write the bitrate number, switch back to Avid DNxHD, and make Streamclip convert this video.

The result is that no matter what I do, a one-and-half minute video often has a bitrate of 180mb/s while a 70 minute video could not convert to more thatn 10 MB/s. Could you help me with this problem, please? Is there any standard way to convert a video to a high bitrate?

So you arbitrarily want 80 Mb/s? You don't care what codec? What frame size? Frame rate? Quality?

I am trying to convert an mp4 video from .mp4 to .mov.

Any codec will be fine as long they work, although someone recommended me to use some type of DNxHD codec. The only website where I know I could download a DNxHD codec is on avid.com where it comes with a DivX player. If there are any good websites where I can download a better DNxHD codec, I will be glad to know. If there are any codec which would make changing the bitrate easier, please tell me.

I am aiming to have a screen resolution of 1920x1080 pixels.

By the way, the bitrate should be at least 50 MB/s. This the main problem which I have.

I forgot to mention that I would set my frame rate to either 24 or 25 frames per second.

But you know that you won't raise the visual quality by re-encoding with more bitrate than the original? Is the subjective quality important at all, or are you only going to test possible transfer and playback issues for high bitrates, and the video content is less important?

There are many codecs available which compress less efficiently than e.g. MPEG-4 AVC (H.264). "Raw" uncompressed video formats will create huge videos with massive bitrates, wasting a lot of harddisk space. Lossless compression formats still need a lot more bitrate, but you may need to find a codec which is available for both VfW under Windows and for QuickTime (possibly even on a Mac); the Ut Video Codec Suite may be the one and only available exception.

The easiest way to bloat up the bitrate without visual advantage is to re-encode with ffmpeg and libx264 into a MOV container, using a matching target bitrate paired with VBV parameters, or a very low CRF (like 6), or even lossless mode (but QuickTime may not support that for decoding, and even regular H.264 will require some restrictions to comply with the limited QuickTime decoder).

In addition, there may be multiplexers which can fill up the container with "stuffing bytes" to simulate a constant high bitrate, but I don't know any for the MOV container.

I'm guess this will be broadcasted, as I've seen others say that broadcasters demand at least 50Mbit video. It's a stupid if you use something like x264 with decent setting but I can see why they demand it.

What a "newpball"-style poll!

Sounds like there is a lot still to this story, and assumptions, that still hasn't been said. Background info? Sample clip?

Add noise to video (maybe to luma plane only).

So how exactly can I use any of these codecs to change the bitrate? What should I do so that I could do so via Streamclip?

It is not clear what are you trying to reach - also terms used by you may be different depends on context (video file as video + container or plain es video). Without knowing context i cant provide anything above already provided.

[LigH.de]

Some of them will already waste enough space by using them, because they compress not so efficiently, or not at all.

Others will only waste so much if you configure them to store the video much more exactly than necessary not to recognize any difference to the original.

Still the question: Why such a waste?

I am hoping to get a bitrate of 50 mb/s or more with the frame rate of 24 or 25 frames per second. Any file size would be good, although I would aim for at least 100 GB. I am trying to convert from an mp4 video(created by Windows Movie Maker) to the .mov file. You can look for the rest of the context above. I have trouble knowing how exactly to convert the bitrate. Whenever I try to convert a one-and-half minute video, it usually as the bitrate of 180 mb/s and a 70-minute video with no more than 10 mb/s no matter what options I use or the compressors I select.

Do you know how to convert the bitrate?

Go for MPEG-2 MP@HL, maximum speed allowed by MPEG-2 is 80Mbps, reduce GOP length and don't use B frames, add low amount of noise to luma plane.

Do you know how to convert the bitrate?

You use a codec that supports bitrate based encoding then set the desired average bitrate. Since you require a MOV file you are limited to codecs that are compatible with that container. If you just want an arbitrarily big file you can use ffmpeg to save as uncompressed YUV 4:2:2:

ffmpeg -i input.mp4 -vcodec rawvideo -pix_fmt uyvy422 -vtag 2vuy output.mov

That's about as big and high quality as your video will get.

I tried inserting this code into the command prompt. The only problem is when I simply type this code, it would not accept this command.
I have a very limited knowledge of programming as I ma taking an introductory course in Java. Should I add something in the command prompt, like selecting directories, before using this code? Thank you for the code.

Download ffmpeg, run command line in same folder where ffmpeg is located.
Alternatively - use notepad or similar text editor, copy above code and save (on windows with extension cmd or bat).
I slightly modified code in a way that you can drag and drop files on it so it behave more like converter - new file has name with added _HBR.

ffmpeg -i %1 -vcodec rawvideo -pix_fmt uyvy422 -vtag 2vuy %~n1_HBR.mov

I dragged and dropped this textfile into the ffmpeg execuatable file. Was this what I was supposed to do?

If so, how do I convert the mp4 file to the .mov file?

No. That text should be in a file with the extension .BAT -- a batch file. Then you drag and drop your video file onto batch file.

So far I wrote this code in .BAT. I dragged-and-dropped into the ffmpeg file menu. Did I do this well?

Thank you, but I have another problem. When I try to convert a video, I kept getting an error message which reads "Can't set the compression buffer". I usually use a single video for testing, but I didn't get such an error message until one or two days ago. How can I fix this? I hope to get this fix quickly.

It sounds like you did the right thing. Did you get a new video file?

You can add a second line to the batch file so it doesn't close the window automatically. That way you can examine the output from ffmpeg for error messages. Add PAUSE on the second line.

I forgot to mention that the error message is from Streamclip, which I try to use to convert.

I'm not an expert by any stretch of the imagination so be gentle with any responses. So have you tried this?

ffmpeg -i original.mp4 -vcodec huffyuv output.mov

Compare my original file with the output file:

I have just one more problem, when I search of the compressor menu in Streamclip 1.2 ,original or beta(I temporarily switched to the beta version to get around the error message specified above), I could not find the ffmpeg one. I could only find Quicktime, h.264, or Ut Video related compressors.

How do I use the ffmpeg to convert the bitrate?

[jagabo]

ffmpeg is a standalone command line program. It uses x264 as its h.264 encoder.

[GroundHogSOS]

ffmpeg is a standalone command line program. It uses x264 as its h.264 encoder.

So does it mean I should download the h.264 encoder or should I just selesct "h.264" as the compressor?

P.S. : I should not that I download Stramclip 1.2 from squared5.com. Was it the right website to download Streamclip?

[jagabo]

No, it means you should run ffmpeg from the command line as indicated earlier in this thread. Put Pandy's batch file in the same folder as ffmpeg.exe, drag/drop your video file onto the batch file.

This has nothing to do with StreamClip.

1. Download FFMPEG portable here: https://www.videohelp.com/software/ffmpeg
2. Unzip it
3. Navigate to the directory containing ffmpeg.exe and place your video there
4. Navigate back to the ff-prompt and click it
5. Type this message into the newly opened window: ffmpeg -i yourfilename.mp4 -vcodec huffyuv youroutputfilename.mov
6. Watch the progress window
7. When finished, your modified (new) file will be in the same directory as ffmpeg.exe

I just did another test using an 18,000KB .mp4 and the conversion turned it into a 1.18GB .mov with a bitrate of 349MBs.

You wanted big; yes?
