And so you accept raw footage and yous want to edit so upload information technology?I want to enquire if is there a manner to render them two times with same quality.
In that case, rendering the same video twice is a tedious procedure and you should be able to edit the video directly. That is considering processing the same footage twice may degrade the quality much more than bringing down the size and quality once.
If you have issues editing the .mp4 files considering of their size, so it is possible to process the raw footage in one case and then use the processed footage.
The first render depends on the overall quality of the mp4's, which consists of resolution and bitrate as the two of import things, then codec, which I will address afterward.
If y'all want to keep the same quality only a smaller file size, you will have to lower the bitrate to a point where the divergence between the raw mp4 and the rendered file are the lowest in terms of frame details. This point (bitrate) is a preference and it depends on where you lot think is the best bitrate.
My ideal bitrate for a 1080p youtube video is 10-xx Mbps using H.264 codec. When you upload the video, youtube will process the video again to a bitrate of around 8-10 Mbps to save space.
The bitrate also depends on what contents of the video is. A video game recording might need a bigger bitrate rather than an animation or a recording of your monitor screen. The college the bitrate of the raw mp4 files, the college the bitrate of the processed video needs to be to contain all the details.
The next thing you need to find out is the codec of the original mp4. If it is a lossless (or uncompressed) file, then you lot can lower the file size to a much lower value by rendering to whatsoever of your preferred codecs.
If the video is encoded with an H.264 codec, which the most popular of the internet codecs, then you tin can either lower the bitrate using the same H.264 codec. Since H.264 is programmed to be efficient and utilize the virtually of the bitrate, lowering its bitrate will considerably reduce the quality. Alternatively, you tin can encode using the newer and more than efficient H.265 or HEVC (High Efficiency Video Codec) which tin concur higher quality with a lower bitrate. In some cases, I've seen H.265 videos accept the same quality but have half the size of the same video but encoded in H.264. The just disadvantage of encoding in H.265 is since the encoder needs more arithmetical operations to compress the footage, the rendering takes longer than H.264, just not very much.
If you want, yous can skip rendering the first time by editing the raw footage and then rendering the video using H.265.
I recommend you to render using the 'MAGIX AVC/AAC MP4' format, more than precisely the 'Internet Hard disk' 1080p/720p (depending on your concluding resolution) and 25-29.97 fps (depending on the framerate of the original video). Then, if you want H.264, choose Mainconcept AVC, then either Variable or Constant bitrate (constant for a shorter render time). If you want H.265, choose NV Encoder (NV for Nvidia). NV Encoder only accepts a variable bitrate, because of the calculations between frame details that need to be done. You lot tin can choose your preferred bitrate in the 'average (bps)' space, then choose a higher bitrate in the 'maximum (bps)' space. This means that the bitrate is not locked to 10mbps, for example, simply varies to a higher bitrate in the case that a frame contains more than item.
I also recommend you to experiment using a 10-second video prune and render multiple bitrates to see which values fit your footage all-time.
Let me know if you lot meet any bug or have any other questions.

And so you have raw footage and yous want to edit then upload it?I want to ask if is there a mode to render them ii times with aforementioned quality.
In that example, rendering the same video twice is a wearisome process and yous should be able to edit the video directly. That is because processing the same footage twice may dethrone the quality much more than bringing down the size and quality in one case.
If yous accept problems editing the .mp4 files because of their size, then it is possible to process the raw footage one time and and then use the processed footage.
The first render depends on the overall quality of the mp4's, which consists of resolution and bitrate equally the two important things, then codec, which I will address after.
If y'all desire to keep the same quality but a smaller file size, you volition accept to lower the bitrate to a signal where the deviation betwixt the raw mp4 and the rendered file are the lowest in terms of frame details. This signal (bitrate) is a preference and it depends on where y'all think is the best bitrate.
My ideal bitrate for a 1080p youtube video is x-20 Mbps using H.264 codec. When you lot upload the video, youtube will process the video again to a bitrate of around eight-10 Mbps to save space.
The bitrate besides depends on what contents of the video is. A video game recording might need a bigger bitrate rather than an animation or a recording of your monitor screen. The higher the bitrate of the raw mp4 files, the college the bitrate of the candy video needs to be to contain all the details.
The side by side thing you demand to find out is the codec of the original mp4. If it is a lossless (or uncompressed) file, then yous tin can lower the file size to a much lower value by rendering to whatever of your preferred codecs.
If the video is encoded with an H.264 codec, which the well-nigh popular of the internet codecs, then you tin either lower the bitrate using the same H.264 codec. Since H.264 is programmed to be efficient and use the most of the bitrate, lowering its bitrate will considerably reduce the quality. Alternatively, you can encode using the newer and more efficient H.265 or HEVC (Loftier Efficiency Video Codec) which can hold college quality with a lower bitrate. In some cases, I've seen H.265 videos take the same quality but accept half the size of the same video only encoded in H.264. The only disadvantage of encoding in H.265 is since the encoder needs more arithmetical operations to compress the footage, the rendering takes longer than H.264, but non very much.
If you desire, you can skip rendering the first fourth dimension by editing the raw footage then rendering the video using H.265.
I recommend you to return using the 'MAGIX AVC/AAC MP4' format, more precisely the 'Internet HD' 1080p/720p (depending on your last resolution) and 25-29.97 fps (depending on the framerate of the original video). Then, if you want H.264, choose Mainconcept AVC, then either Variable or Abiding bitrate (constant for a shorter return time). If you want H.265, choose NV Encoder (NV for Nvidia). NV Encoder only accepts a variable bitrate, because of the calculations between frame details that need to be washed. You can choose your preferred bitrate in the 'boilerplate (bps)' space, then choose a higher bitrate in the 'maximum (bps)' space. This means that the bitrate is non locked to 10mbps, for example, but varies to a college bitrate in the case that a frame contains more particular.
I also recommend you to experiment using a 10-second video clip and return multiple bitrates to run into which values fit your footage best.
Allow me know if you encounter whatever problems or take any other questions.
