Yes, by setting both the video and audio codecs to 'Copy (No Re-encoding)', the streams are transferred directly without quality loss. ### What is the maximum file size supported? The tool supports MP4 video files up to 100 MB in size. ### Which video codecs can I choose for the AVI file? You can choose Copy, H.264, H.265/HEVC, MPEG-4, MS MPEG-4 V2, or MS MPEG-4 V3 (DivX). ### What does the CRF Quality setting do? It controls the visual quality during re-encoding; lower values (down to 18) produce higher quality but larger files. ### Can I convert audio to MP3 inside the AVI container? Yes, select MP3 from the audio codec dropdown options before starting the conversion. ## Related tools - [AVI to MP4 Converter](https://elysiatools.com/en/tools/avi-to-mp4): Convert AVI video files to MP4 format - [Batch Video Converter](https://elysiatools.com/en/tools/video-batch-converter): Convert multiple video files between different formats like MP4, WebM, MKV, AVI, MOV with quality settings and batch processing - [Video to APNG](https://elysiatools.com/en/tools/video-to-apng): Convert video clips to APNG (Animated PNG) format with transparency support and better quality than GIF - [Video to GIF Optimized](https://elysiatools.com/en/tools/video-to-gif-optimized): Convert videos to optimized GIF format with advanced compression settings - [Video to Image Sequence](https://elysiatools.com/en/tools/video-to-image-sequence): Extract video frames as an image sequence with customizable frame rate, quality, and output format - [Video Cutter](https://elysiatools.com/en/tools/video-cutter): Cut and trim video clips with precision, supporting multiple formats and quality settings - [FLV to MP4 Converter](https://elysiatools.com/en/tools/flv-to-mp4): Convert FLV video files to MP4 format - [MKV to MP4 Converter](https://elysiatools.com/en/tools/mkv-to-mp4): Convert MKV video files to MP4 format ## Samples - [Video AV1 Samples](https://elysiatools.com/en/samples/video-av1-samples): Sample video files encoded in AV1 format - [Video H.264 Samples](https://elysiatools.com/en/samples/video-h264-samples): Sample video files encoded in H.264 (AVC) format - [Video H.265 Samples](https://elysiatools.com/en/samples/video-h265-samples): Sample video files encoded in H.265 (HEVC) format - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion ## Related content - [Audio Encoding and Format Conversion Tools](https://elysiatools.com/en/hubs/audio-convert): Compare audio format conversion, bitrate changes, sample-rate conversion, codec swaps, and export tools in one hub for delivery and archive workflows. - [Video-to-Audio and Animation Conversion Tools](https://elysiatools.com/en/hubs/video-convert): Compare tools that turn video into audio, extract video streams, and convert between short-form video and animated image formats in one hub. - [Audio Editing and Cleanup Tools](https://elysiatools.com/en/hubs/audio-utility): Compare audio trimming, silence removal, fades, mixing, and denoise tools in one hub for podcast, voiceover, and music cleanup workflows. - [Video Preview, Extraction, and Subtitle Tools](https://elysiatools.com/en/hubs/video-utility): Compare video preview generation, stream extraction, audio extraction, subtitle translation, and quick flip tools in one hub for lightweight video prep workflows.
