Convert MTS to MP4 Quickly with Aiseesoft MTS Converter

Convert MTS to MP4 Quickly with Aiseesoft MTS ConverterMTS is a high-definition video file format commonly produced by AVCHD camcorders from brands such as Sony and Panasonic. While MTS offers excellent video quality, it’s not universally supported across devices and platforms. MP4 (MPEG-4 Part 14) is one of the most compatible, widely accepted formats for playback, editing, and streaming. Converting MTS to MP4 makes your videos easier to share, edit, and play on smartphones, tablets, web platforms, and video editors. This guide explains why you might convert MTS to MP4, introduces Aiseesoft MTS Converter, and provides a step-by-step walkthrough, plus optimization tips and troubleshooting.

Why convert MTS to MP4?

• Compatibility: MP4 is supported by nearly all devices, operating systems, and web services.
• Smaller file sizes: With efficient codecs (H.264/H.265) MP4 often provides a good balance of quality and compression.
• Editing and sharing: Most video editors and social platforms accept MP4 natively, simplifying workflows.
• Playback performance: MP4 is optimized for streaming and hardware decoding on mobile devices.

What is Aiseesoft MTS Converter?

Aiseesoft MTS Converter is a desktop video conversion tool designed to handle AVCHD (MTS/M2TS) files and convert them to common formats like MP4, MOV, AVI, MKV, and more. It focuses on preserving quality while offering speed and batch processing features. Key user-facing capabilities typically include:

• Batch conversion of multiple MTS/M2TS files.
• Output presets for devices (iPhone, Android, tablets, game consoles).
• Adjustable video/audio parameters (codec, bitrate, resolution, frame rate).
• Basic editing tools: trimming, cropping, merging, rotating, watermarking.
• Preview window and snapshot capture.
• Hardware acceleration support to speed up conversion on compatible GPUs.

Preparing for conversion: what you’ll need

• A Windows or macOS computer with enough free disk space (source files and converted copies).
• The Aiseesoft MTS Converter application installed and updated.
• Source MTS files copied from your camcorder or memory card to your computer (recommended to avoid reading issues).
• Optional: a target device profile or knowledge of desired export settings (resolution, codec, bitrate).

Step-by-step: Convert MTS to MP4 quickly

1. Install and open Aiseesoft MTS Converter.
2. Click “Add File” (or drag and drop) to import one or more MTS/M2TS files.
3. At the bottom or side, choose the output format. Select MP4 and then pick a preset that matches your target device or resolution (e.g., “MP4 — H.264 1080p”).
4. If needed, click “Settings” (or the gear icon) to adjust video parameters:
   • Codec: H.264 (AVC) for broad compatibility, or H.265 (HEVC) for smaller sizes if your target supports it.
   • Resolution: keep original resolution for quality, or downscale to 1080p/720p for smaller files.
   • Bitrate: higher bitrate = better quality but larger files; use variable bitrate (VBR) if available.
   • Frame rate: usually keep original (often 25/30/60 fps).
5. Use editing tools if you want to trim unwanted parts, crop black bars, rotate, or add a watermark. Merge files if you need a single continuous MP4.
6. Choose an output folder.
7. If available, enable hardware acceleration (Intel Quick Sync, NVIDIA NVENC, or AMD) to speed up conversion.
8. Click “Convert” (or “Start”) and wait. Conversion time depends on file length, codec settings, and whether hardware acceleration is enabled.

Tips to speed up conversion without losing quality

• Enable GPU/hardware acceleration if your system supports it.
• Convert in parallel batches only if your CPU has multiple cores and the software supports concurrent encoding.
• Use H.264 hardware encoders (NVENC/Quick Sync) which are much faster than CPU-only x264.
• Reduce unnecessary upscaling: convert at the source resolution unless you need a different size.
• Use one-pass encoding at an adequate bitrate for faster output; two-pass offers marginally better quality at the same bitrate but takes longer.
• Close other CPU/GPU-intensive apps during conversion.

Recommended settings for common needs

• General playback (balance quality & size): H.264, 1920×1080 (if source is HD), 8–12 Mbps for 1080p.
• Mobile devices: H.264, 1280×720, 3–5 Mbps.
• Highest quality archiving: H.264 or H.265, keep original resolution, high bitrate (20+ Mbps).
• Streaming/web upload: follow the platform’s recommended bitrate/resolution; MP4 H.264 baseline/main profiles are safest.

Troubleshooting common issues

• No sound after conversion: check audio codec (AAC is preferred), sample rate, and bitrate; ensure the output preset includes audio.
• Playback stutters: try a lower bitrate, ensure hardware acceleration is enabled, or use a different player (VLC).
• Failed imports from camera: copy files from the card to the computer first; ensure the MTS files aren’t fragmented or corrupted.
• Large output files: reduce bitrate, convert to H.265 if supported, or reduce resolution.

Alternatives and when to use them

If you need free tools, consider HandBrake (open-source, powerful presets, H.264/H.265 support) or VLC (basic conversion). For professional workflows with deeper control over codecs and color, tools like Adobe Media Encoder or DaVinci Resolve may be preferable.

Final thoughts

Converting MTS to MP4 is often necessary to maximize compatibility and usability. Aiseesoft MTS Converter streamlines the process with presets, editing tools, and hardware acceleration to make conversions both quick and straightforward. Choose appropriate output settings based on your destination (playback device, editing, or web), enable hardware acceleration for speed, and use sensible bitrates to balance quality and file size.
